God's will is something that all men are supposed to obey because despite what, disobedience is the key the devil wants to use and luck us up for his own selfish purpose.
Every will that comes from God is Coming to us with a purpose, for were ever there is will there is purpose, the will of the lord is like God's mind.
And if you are not a believer, you won't know how to obey God's will, because you will obey God's will only when you know and believe in God.
We owe God a total obidience and submission as our father and our maker, if we don't obey his will we would go astray.
